The method comprises the following steps: generating a tower structure through the tower parameters to obtain the dead weight of the tower; namely, generating a tower structure through the tower parameters, firstly simulating main load-bearing structural members of the tower through the structural parameters of the tower, and then further refining the simulation on each main load-bearing structure. The whole tower meets the strength and rigidity requirements, and the dead weight of the tower is obtained through the weight calculation of the main bearing structure. Obtaining an external load borne by the tower, wherein the external load comprises: wind load (can decompose into horizontal component and vertical component), cable wire load (be the pulling force to steel pipe shaft tower from the cable wire promptly), icing load (indicate that there is the likely operating mode that covers ice sheet or ice cone on the cable in winter) to the external load of shaft tower carries out the atress analysis, generates the structural parameter of shaft tower, the structural parameter of shaft tower includes: the front distance and the side distance between two feet of each tower are the position relation of a main structural member (the main structural member is a main bearing member of the tower), and the tower structure can be simulated through structural parameters of the tower. Therefore, the dead weight of the tower can be analyzed, and the dead weight of the tower and the external load borne by the tower can influence the structure of the steel pipe tower foundation, so that the input conditions of the stress analysis of the steel pipe tower foundation are all input conditions.
Preferably, the load composition of the tower foundation comprises vertical stress and horizontal stress; the method specifically comprises the following steps:
the method comprises the steps of obtaining the dead weight of a tower, the dead weight of a ground wire, the component of the tension of the ground wire in the vertical direction and the component of wind load in the vertical direction, and obtaining the vertical stress of a steel pipe tower foundation;
and obtaining the component of the tension of the ground wire in the horizontal straight direction and the component of the wind load in the horizontal direction, and calculating to obtain the horizontal stress of the steel pipe pole tower foundation.
That is: analyzing the stress of the steel pipe tower foundation in the vertical direction and the horizontal direction, wherein the vertical stress comprises the dead weight of the ground wire, the dead weight of the tower, the component of the tension of the ground wire in the vertical direction and the component of wind load in the vertical direction, so as to obtain the vertical stress of the steel pipe tower foundation; the horizontal stress comprises a component of the tension of the ground wire in the horizontal straight direction and a component of the wind load in the horizontal direction, and the horizontal force born by the steel pipe tower foundation is analyzed to obtain the horizontal stress of the steel pipe tower foundation. The resulting foundation load includes horizontal and vertical forces on the tower.
And carrying out stress analysis aiming at the steel pipe pole tower foundation, and carrying out corresponding stress combination according to geological conditions of the installation area and the installation position of the steel pipe pole tower foundation to obtain the stress in the horizontal direction and the stress in the vertical direction.

The proper tower foundation type can be further selected according to the geological conditions of the installation region and the installation position of the steel pipe tower foundation.
When the load of the steel pipe pole of the pole tower is manually input, the load is:
first, a tower type is set.
Secondly, the load is manually input, the basic load can be a standard value or a design value, and the standard value is the actual external load born by the tower structure under the specified meteorological conditions. The design value is obtained by multiplying the standard value by a predetermined coefficient. When the stress of the tower is only one, the stress is multiplied by a certain coefficient to be converted into a design value. The specific reasons are as follows:
the tower structural loads are divided into permanent loads and variable loads, the permanent loads including: the dead weight of the tower structure and the dead weight of the ground wire; the variable load includes: tension and wind load of the ground wire and ice coating load.

Also, for the stress analysis of the steel pipe tower foundation, it is common to have a foundation force with multiple working conditions (i.e., having multiple stress forms, i.e., having multiple stresses). Then, when there is only a single (one) force, it is also necessary to convert the force into a design value, where the conversion parameter of the vertical force may take a conservation value (design value conversion standard value, 1.2 if the structure is favorable, 1.0 for the gravity component coefficient, or 1.4 if the design value is converted by the 1.2. Standard value, for example, 1.4 if the gravity due to ice coating changes), or 1.3 or other empirical value.
Thirdly, selecting the type of the tower foundation through the stress calculation result of the tower foundation and the connection mode of the tower foundation and the tower. Types of tower foundations include: step type, filling pile, digging type, sleeve type, etc.

The foundation bearing capacity, i.e. the maximum downforce, is obtained by the soil type. The base of how deep can also be calculated from the soil's gravity and pull-up angle can be sufficient to resist the specified pull-up force.
Preferably, step 103 specifically includes:
determining the concrete grade, the main column reinforcement grade, the bottom plate reinforcement grade, the step reinforcement grade and the main column stirrup grade according to the address conditions; the higher the concrete grade is, the stronger the pressure resistance is, and the less concrete is required under the same pressure resistance requirement. In contrast to concrete, the steel bar can only resist tension, and the higher the grade, the stronger the tensile capacity. The less the amount of rebar is required for the same tensile capacity requirement. But the reinforcement content (the proportion of the area of the reinforcement in the cross-sectional area of the member) must meet the standard requirements. The stirrup is subjected mainly to external forces perpendicular to the main bar, so-called shearing forces. When the grade of the main column steel bars is obtained, different grade of the bottom plate steel bars, grade of the step steel bars and grade of the main column stirrups can be automatically matched, and the steel bars in the selected grade can be directly selected at the interface according to actual conditions, for example, the steel bars in the selected grade are not existed, so that the grade may need to be reduced to increase the amount of the steel bars.

That is, in the three-dimensional model, different materials are represented by different colors, such as concrete and steel are represented by different colors. The steel or concrete with different intensities can only be checked to obtain the corresponding attribute values, the three-dimensional model can not be directly seen from the three-dimensional graph, the structure of the foundation of the steel pipe pole tower can be intuitively displayed, and the three-dimensional model is converted into a two-dimensional engineering graph for manufacturing and construction.
The main structure of the steel pipe pole tower foundation is independently generated, and then the main structure is effectively integrated into a whole for display according to the structural data of each main structure. Many structures of the tower adopt a plurality of main columns, each main column corresponds to one stress foundation component, each stress foundation component can be completely independent or can be mutually related, and the structural data indicates the relative positions and the relativity (such as whether a connecting beam exists or not) of the stress foundation components.
